Proven efficacy for reducing subsequent stroke in patients with prior TIA or stroke2,3
*25 mg twice daily.
†European Stroke Prevention Study 2 (ESPS 2): A randomized, double-blind, placebo-controlled, 24-month trial comparing 25 mg low-dose aspirin alone, 200 mg ER-DP, and the 2 agents in combination (AGGRENOX), in 6,602 patients with prior ischemic stroke or TIA. All treatments were given twice daily.2
‡Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS): A double-blind, 2-by-2 factorial trial in which 20,332 patients were randomized to 25 mg of aspirin plus 200 mg of ER-DP twice daily or to 75 mg of clopidogrel once daily over a mean duration of 2.5 years. Trial failed to meet its primary endpoint, and thus the comparison to clopidogrel was not conclusive.3
TIA=transient ischemic attack; ER-DP=extended-release dipyridamole.
